Agilent E4421B RF Signal Generator
Quick Reference Guide
Main Controls
The first three buttons listed below are the most
often used. Many buttons bring up a softkey
menu to the right of the screen. Numeric values
are entered using the keypad followed by pressing
a units selection on the softkey menu to the
right of the display.
- PRESET This key restores the generator to a
known state. This is a good place to start. - Frequency Hit this key, followed by entering a
frequency value on the keypad and units (e.g.
MHz) on the softkeys to the right of the display. - Amplitude Allows entry of an amplitude level.
- RF On/Off Turns the output signal on and off.
Current state is shown in the display below the
amplitude box. - Mod On/Off Turns the modulation on and off.
- AM/FM/PM These buttons bring up softkey menus to
configure the modulation frequencies/etc (for
internal generator use), and modulation
sensitivities (e.g. kHz/V) for external
modulation. - EXT1/EXT2 Input connectors for externally
applied modulating waveforms. Apply 1V peak
signals to achieve modulation deviations
programmed using AM/FM/PM menus.
Overview
- The E4421B is an RF signal generator covering 250
kHz through 3 GHz. (usable down to 100 kHz) - It has synthesized tuning allowing frequency
resolution to 0.01 Hz. - The RF output level can be set from -136 dBm to gt
10 dBm with a resolution of 0.02 dB. - Basic AM, FM, and PM modulation is provided,
including a built-in modulation source producing
sinewaves from 0.1 Hz to 50 kHz and squarewaves,
pulses, and noise modulation from 0.1 Hz to 10
kHz. - Alternatively, modulating waveforms can be input
externally. FM input response is from DC to 10
MHz, PM is DC to 1 MHz, and AM is DC to 10 kHz.
